The mass distribution in the Galactic Centre from interferometric astrometry of multiple stellar orbits

GRAVITY Collaboration, R. Abuter, N. Aimar +62

The stars orbiting the compact radio source Sgr A* in the Galactic Centre are precision probes of the gravitational field around the closest massive black hole. In addition to adap…

Deep Images of the Galactic Center with GRAVITY

GRAVITY Collaboration, R. Abuter, N. Aimar +65

Stellar orbits at the Galactic Center provide a very clean probe of the gravitational potential of the supermassive black hole. They can be studied with unique precision, beyond th…

Flaremodel: An open-source Python package for one-zone numerical modelling of synchrotron sources

Y. Dallilar, S. von Fellenberg, M. Bauböck +13

Synchrotron processes, the radiative processes associated with the interaction of energetic charged particles with magnetic field, are of interest in many areas in astronomy, from…

The GRAVITY Young Stellar Object survey. VII. The inner dusty disks of T Tauri stars

The GRAVITY Collaboration, K. Perraut, L. Labadie +55

These protoplanetary disks in T Tauri stars play a central role in star and planet formation. We spatially resolve at sub-au scales the innermost regions of a sample of T Tauri's d…

GRAVITY K-band spectroscopy of HD 206893 B: brown dwarf or exoplanet

J. Kammerer, S. Lacour, T. Stolker +94

We aim to reveal the nature of the reddest known substellar companion HD 206893 B by studying its near-infrared colors and spectral morphology and by investigating its orbital moti…

The GRAVITY young stellar object survey V. The orbit of the T Tauri binary star WW Cha

GRAVITY Collaboration, F. Eupen, L. Labadie +60

The young T Tauri star WW Cha was recently proposed to be a close binary object with strong infrared and submillimeter excess associated with circum-system emission. This makes WW…
